Intel Core Ultra 9 285K Linux Memory DDR5 Performance Testing
Following last week's launch testing of the Intel Core Ultra 9 285K and Core Ultra 5 245K Arrow Lake desktop processors, the next area I've been exploring deeper has been the DDR5 memory performance including with CUDIMMs.
With the 0805 BIOS for the ASUS ROG MAXIMUS Z890 HERO I was still encountering some application hangs and segmentation faults particularly when using DDR5-8000 memory. With not focusing too much on desktop memory reviews at Phoronix given that there typically isn't a Linux angle from it, it's mostly a collection of DIMMs I've bought over time or a few have been received from vendors. With this Intel Core Ultra 9 285K + ASUS ROG MAXIMUS Z890 HERO desktop I ran a variety of benchmarks on these different DIMMs in their XMP 1 profiles (or CUDIMM DDR5-6400 default given its lack of XMP profiles) for seeing how the Arrow Lake performance is impacted for a range of workloads.
